%signature diversa da matlab per problema handle funzioni (comunque se piu' tempo da riprovare)
function xoverKids = crossoversinglepoint (parents)

      %costanti
      N_BIT_DOUBLE = 64;

      %una variabile d'appoggio
      nvars = columns (parents);

      concatenated_parents = ;

      %n e' il singolo punto del crossover
      %n potra' andare da 1 a ((N_BIT_DOUBLE * nvars) - 1)
      n = double (uint64 ((((nvars * N_BIT_DOUBLE) - 2) * rand ()) + 1));

      %crossover a singolo punto
      concatenated_xoverKids = strcat (substr (concatenated_parents (1, :), 1, n), substr (concatenated_parents (2, :), (n + 1)));

      xoverKids = __ga_concatenated_bitstring2doubles__ (concatenated_xoverKids);
endfunction
